How To Wire A Lighting Circuit In A House

Once you have mastered the basics.

How to wire a lighting circuit in a house. This is how you wire a light pendant. Lighting circuits typical lighting circuits are designed as 15 amp 120 volt or 20 amp 120 volt. Next twist together like colored wires coming from the fixture and the wall or ceiling such as black with black and red with red then screw a wiring cap over the exposed ends. This does not include the light switches which should be wired in switch wire which contains 2 red cores.

Push the long wire through the hole in the top of the special green wire connector and connect the remaining wires to it by twisting the connector clockwise until it s tight. Without it the blue wire indicates a neutral wire. Using 1mm cable is allowed for up to 95meters of circuit length. Leave one bare ground wire long and snip the rest to 6 in.

Once you have read the safety tips a good place to start is by getting up to speed on the basic radial lighting circuit. You must use the brown slewing to indicate the switched line wire. Another major defect of series lighting circuit is that as all lamps or bulbs are connected between line l and neutral n accordingly if one of the light bulb gets faulty the rest of the circuit will not work as the circuit will be open as shown in fig below. The radial lighting circuit has 3 common wiring options which may be mixed at will.

If your house is newer you may find that the white from d5 to d4 and the one from d4 to c4 have been colored to show that they are not neutrals. Here you can see there is a cut in the line wire connected to lamp 3 so the bulb is switch off and the rest circuit is working. Planning the electrical circuits for a home will depend on a few factors such as the location or area of the home where the circuits will be installed and the devices that will be connected to the circuit. The source is at the dimmer and the hot wire is spliced to one hot wire on the device.

Loop in as per diagram above. The other wire from the dimmer is spliced to the black cable wire which runs on to the hot terminal on the light. Once connected the light pendant should look like this click to enlarge. If you have longer lengths to cover 1 5mm squared cable can be used and the maximum length allowed using this is 110m.

Switch c4 passes hotness to one of the travelers red or white that go back to switch d4 which in turn passes or does not pass such hotness on to light d5 on the black wire. Sometimes called a loop in circuit this shows how power is distributed around the lighting circuit via the ceiling roses or junction boxes and how to wire a light switch into the circuit. To wire a light in your home start by switching the appropriate circuit in your fuse box to off so you can work safely with the wires. A lighting circuit can serve up to 12 x 100w bulbs.

The circuit is fed to each lamp fitting in turn and a separate cable connects from the fitting to the switch.
